Background: Individuals with untreated hearing loss often experience cognitive decline as a result of increased cognitive load and reduced sensory stimulation. Despite the well-established link between untreated hearing loss and cognitive decline in older adults, its impact on cognition in young and middle-aged adults has not been systematically examined. Given the Lancet Commission’s identification of midlife hearing loss as the leading modifiable risk factor for dementia, early identification of cognitive decline is essential. This review explored the cognitive impact of untreated hearing loss in adults. Method: A comprehensive search was conducted in PubMed, Scopus, Web of Science, and EMBASE to include studies comparing cognitive function between adults with normal hearing and those with untreated hearing loss aged 18–65 years. The methodological quality of the included studies was examined via the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. Pooled mean differences and heterogeneity were analysed for each domain. Results: Seven studies included in the qualitative synthesis had “moderate” to “strong” methodological quality. The cognitive domains assessed in these studies were global cognitive function, memory, attention, and executive function. Of these, six were eligible for meta-analysis, which revealed a small but statistically significant decline in overall cognitive performance and memory and executive function among adults with untreated hearing loss. Conclusions: Cognitive vulnerabilities exist in young and middle-aged adults with untreated hearing loss. Hence, incorporating cognitive assessment into routine audiological evaluation may enable earlier intervention and delay the future burden of Alzheimer’s disease and related dementias in such a population.

Background/Objectives: Subjective tinnitus, defined as the perception of sound without an external source, is a common and often debilitating condition. In the absence of pharmacotherapy, disease management guidelines recommend counseling interventions to alleviate tinnitus-related distress and improve patient outcome. This study evaluated the benefit of guideline-compliant counseling provided by “Meine Tinnitus App”, a smartphone-based application, for the treatment of subjective tinnitus. Methods: A randomized controlled study was conducted in 204 patients with confirmed chronic subjective tinnitus enrolled at 33 ear, nose and throat (ENT) practices in Germany. Tinnitus improvement was evaluated after 10 weeks of intervention (digital counseling in addition to standard care vs. standard care only). The primary endpoint was the change in tinnitus-related distress (measured by the Mini-TQ-12 validated questionnaire). The secondary endpoint was the change in tinnitus-associated daily burden and coping difficulties (measured by the validated BVB-2000 questionnaire). Treatment effects for the primary and secondary endpoints were represented by the estimated marginal means (EMMs). Results: Patients of the intervention group showed a significant reduction in tinnitus-related distress (EMM [95% CI]: 4.5 [3.3–5.8]; p < 0.001) and a significant improvement in tinnitus-associated daily burden and coping difficulties (EMM [95% CI]: 0.5 [0.2–0.7]; p < 0.001) compared to patients of the control group, with large to moderate effect sizes (Hedges’ g between 1.1. and 0.5). These positive treatment effects were confirmed by responder and sensitivity analyses. Additionally, patients with high vs. low app usage showed a greater improvement in treatment effect for both endpoints (p < 0.05), further supporting the health benefits of digital counseling. Conclusions: This study demonstrated the efficacy of tinnitus counseling provided by “Meine Tinnitus App” to alleviate tinnitus-related distress, daily burden, and coping difficulties in patients with subjective tinnitus (German Clinical Trials Register DRKS00025379).

Objective: The aim of the study was to evaluate the validity, clinical applicability, and developmental sensitivity of the Romanian LEESPQ in children with cochlear implants (CIs), by analyzing its association with age at implantation, duration of auditory experience, and implantation laterality, and by comparing the developmental trajectory with that of normal-hearing (NH) children. Methods: The study assesses the validity, reliability, and clinical sensitivity of the LEESPQ in pediatric cochlear implant users. Furthermore, it investigates the associations between total questionnaire scores and key clinical variables, including implantation laterality (unilateral versus bilateral), age at device activation, and duration of implant use. Forty-seven children with CIs (26 boys, 21 girls) were included, with implantation ages ranging from 9 months to 5 years. Of these, 21 received unilateral implants and 26 bilateral implants. Responses were analyzed both in relation to clinical variables and in comparison with available normative data from NH children, in order to delineate potential differences in linguistic developmental trajectories. Results: Findings suggest that the LEESPQ is a reliable and clinically valuable instrument for monitoring post-implant linguistic progress. It provides relevant insights into early auditory access, the linguistic environment within the family, and the development of early verbal production. Scores were significantly influenced by age at implantation and duration of auditory experience, confirming the role of early stimulation and neural plasticity in shaping speech development after cochlear implantation. Conclusions: The LEESPQ demonstrates strong clinical utility as a sensitive tool for monitoring early preverbal and verbal development in children with CIs. By capturing score variations associated with age at implantation, auditory experience, and implantation laterality, the questionnaire provides meaningful insights into early post-implant outcomes and supports individualized rehabilitation planning. These findings highlight the value of the LEESPQ for early outcome assessment in pediatric cochlear implant users.
